Backport

Backport brings content and gameplay features from Minecraft Java 26.3 to older Minecraft versions.

The mod adds new world generation, blocks, furniture, exploration content, gameplay changes, and vanilla bug fixes that can be reproduced on older versions.

Dappled Forest

A new forest biome with:

Poplar trees with red, orange, and yellow leaves
Falling leaf particles and ambient sounds
Fallen trees
Shelf Mushrooms
Red Shrubs
Cold animal variants on versions where they can be implemented

Abandoned Camps

Abandoned Camps generate across the Overworld.

They include:

18 biome-based variants
Different camp layouts
Chests and barrels with loot
Explorer Maps that can lead to camps and other structures

New Blocks and Decoration

Backport adds:

The full Poplar wood set
Poplar signs and hanging signs
Poplar boats and chest boats
Wool stairs and slabs in all 16 colors
Concrete stairs and slabs in all 16 colors
Cushions in all 16 colors
Straw Beds
Shelf Mushrooms
Red Shrubs

Cushions can be placed and sat on.

The Straw Bed lets you sleep through the night without changing your respawn point. It breaks after use.

Explorer Maps

The mod adds 16 Explorer Map types for different structures and locations, including:

Abandoned Camps
Ancient Cities
Mineshafts
Desert Pyramids
Warm Ocean Ruins
Villages
Other vanilla structures

Explorer Maps have their own icons and show the direction the player is facing.

They can be cloned but cannot be zoomed out.

Gameplay Changes

Backported gameplay changes include:

Shelf Mushrooms can be bounced on
Mushroom Stew can be crafted using any two mushrooms
Poplar Saplings and Shelf Mushrooms can appear in Wandering Trader trades
Shields take priority when used together with hoes or shovels
Drowned holding Tridents use melee attacks at close range
Spectators can travel through portals
Changes to mob behavior
Changes to boats and projectiles
Potion and status effect fixes
Various vanilla bug fixes from Minecraft 26.3

Version Differences

Some Minecraft 26.3 changes cannot be backported directly.

Backport does not port engine-level changes such as Vulkan, SDL3, rendering system changes, or changes to Minecraft's internal data formats.

Some features may work differently or be unavailable on older Minecraft versions when the required vanilla systems do not exist.

Configuration

The config allows several features to be enabled or disabled, including:

Dappled Forest generation
Abandoned Camp generation
Wandering Trader trades
Shelf Mushroom bouncing
Mushroom Stew recipe changes
Backported vanilla bug fixes
